** Set an initial water level so the model doesn't start completely dry. This can be done globally with <font color="blue"><tt>Set IWL </tt></font> command or locally with 2d_iwl polygon.
==How can I stabilise 1D features and their 1D/2D boundaries?==
=== 1D open channels including connected bridges and culverts ===
* Split or merge open channel sections - the general advice is to have the length of open channels about 3 to 5 times of their width. Merging very short channels will provide sufficient storage. Splitting long channels into shorter ones with more 1D nodes might smooth the water level slope and the simulated flow rate can become more stable.
